Abstract: In various embodiments, coated infill includes a plurality of infill granules and a preformed coating on the infill granules including a cured polyurethane product of at least one polyurethane prepolymer component and a curative component. The polyurethane prepolymer component includes a reaction product of an isocyanate component including diphenylmethane diisocyanate (MDI) and a polyol component, and has a free isocyanate content (% NCO) from 2 wt % to 12 wt %. The curative component includes water. Methods for making an artificial turf surface using the coated infill are also provided.

Abstract: A cured composition including a reaction product of a mixture that includes an isocyanate component having one or more isocyanates and an isocyanate-reactive component having a butylene oxide based polyol, which has a number average molecular weight greater than 2,000 g/mol and less than 8,000 g/mol and a nominal hydroxyl functionality from (2) to (4). At least (50) wt % of a total weight of alkylene oxides used to form the butylene oxide based polyol is butylene oxide. An isocyanate index of the mixture is from (90) to (150). The cured composition in a cured state exhibits a first tan delta peak between a first temperature range of 50° C. to 0° C. and a second tan delta peak between a second temperature range of 75° C. and 150° C.
